Question

Identify the equation used to determine the amount of heat required to melt $10grams$ of ice:

• A. $Q=m{C}_{sp}△T$
• B. $Q=n△H$
• C. $KE=\frac{1}{2}m{v}^2$
• D. $PE=mgh$
• E. $PV=nRT$

Answer 1

The correct option is A $Q=m{C}_{sp}△T$

The amount of heat per unit mass required to raise the temperature by 1 degree Celsius is called specific heat.

When ice is melted$\to$phase changes to liquid.

So specific heat can be used to determine the heat required mathematically,

specific heat $Q=m{C}_{sp}△T$
